Khorashad Castle is not widely recognized in established encyclopedic sources. The name appears to be derived from the village of Khorashad (also transliterated as Khorāshād), which is located in Birjand County, South Khorasan Province, Iran. In Persian, “castle” is commonly rendered as “qal‘eh,” and many small fortified structures throughout Iran are locally referred to as “Qal‘eh‑e Khorashad.”
No verifiable historical, architectural, or archaeological data about a distinct structure named “Khorashad Castle” has been identified in major academic publications, heritage registries, or reputable reference works. Consequently, detailed information regarding its period of construction, architectural features, cultural significance, or current condition cannot be provided.
Given the lack of reliable documentation, it is possible that the term refers colloquially to a minor or ruinous fortification associated with the Khorashad locality, or it may be a misnomer for a nearby historical site. Further research in regional archives or field surveys would be required to substantiate the existence and characteristics of such a structure.
